CLOSURE FASTENING MECHANISM Filed Sept. 4. 1929 wnmzss v v INVENTOR 2 g 4 QA-Redfi'ekl, 2 BY 22 I M T 3 Y ATTORNEY Patented July 14, 1931 PATENT OFFICE "CHARLES A. REIDFIELD, OF SAN DIEGO, CALIFORNIA CLOSURE FASTENING MECHANISM Application filed September 4, 1929. Serial No. 390,316.-

My invention relates to improvements in door latch controls more particularly to door latch. controls for garage doors and Consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a door latch control which will permit the door to be opened to a slight extent so as to allow the entry of a .person therethrough without 9 necessitating the. opening of said door to its fullest extent.

A further object of my invention is to provide a door latch control that will stop and hold the door in a number of positions providing openings of small and large extent adapted for the entry therethrough of a person or a vehicle respectively.

. A further object of my invention is to provide an. adjustable door latch control which is easily controlled by manual means mounted on the inner side of the door.

p A furtherobject of my invention is to. provide a -do'or'latch control which is easily set up into operative position or disengaged for inoperation. I

A further object of my invention is to provide a device of the type described, which is simple in. construction, has few parts and will not get out of order easily.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming a part of this application, in which Figure 1 is a front elevation view of my invention showing the same mounted for operation,

Figure 2 is a top plan view of my device shown mounted for operation and with the door in closed position,

Figure 3 is a top plan view of my device showing the same mounted on a door moved to open position,

Figure 4 is a sectional view on the line 4-4: of Figure 3, and

Figure 5 is a perspective detail view of a portion of the device.

In carrying out my invention I make use of an ordinary doorsuc'h as that used on garages, houses, barns and the like. In the drawings I have shown such a door at 1 suspended from a "door jamb 2 of a garage or other enclosure by hinged members 3 and 4: and provided with a handle 5 for manually swinging the same about on its hinges.

. Mounted on the door jamb 2 is a pivot bearing bracket 6 providing bearing means for swivelly pivoting the arm 7 thereon by means of pin 8. Pivotally mounted on the other end of the arm 7 by pivot means 9 engaging the lug 10 is a latching bolt 11. This bolt 11 is provided with a series of holes'12 for a purpose soon to be described,

slidable in a guide slide 13 fixedly positioned on the door by fastening means 14 and 15.

Mounted on the opposite or inner side of the door member 1 is a door latch control lever 16 pivotally mounted on the bearing bracket standard 17 mounted on said door as shown in Figures 2 and .3. This door latch control operating lever 16 is pivotally connected. to the locking pin 18 adapted to engage the holes 12 in the bolt 11 through an aperture in said door 1 as more clearly shown in Figure 4. This door latch control operating lever is normally urged to door latching position by the resilient compression spring member 19 as shown in Figures 2 and '3. v

For retaining the parts of my device in operative position and for permitting their disengagement 'to an inoperative position whereby the door maybe swung freely without control of my door latch, I provide an abutment plate mounted as clearly shown in Figure 5, and adapted when swung into operative position to engage the end 21 of the latching bolt 11. This abutment plate 20 is swiveled on the upper leg 22 of the staple bracket 23 as shown'more clearly in Figuref5. This staple bracket 23 provides an aperture24 therethrough so positioned that the latching bolt 11 freely slides therethrough when not supported by the abutment plate 20. y

F rom the foregoing description of the various parts ofthe device the operation thereof may be readily understood. This door latch control as has been previously stated has been designed particularly to be used in connection with garage doors. An examination of Figures 1 and 2 will readily show that the door 1 may be swung open to a slight extent before the latching bolt 11 engages the locking pin 18 and said opening movement is prevented. This permits an opening suiiicient in extent to allow the entry of a person into said garage.

When it is desired to open the door further to permit the passage of an automobile or other vehicle therethrough, the operator depresses the lever 16, manually, thereby raising the pin 18 out of engagement with the end 21 of the latching bolt 11 and permitting said latching bolt to slide beyond said pin 18. The operator then moves the door to a desired open position and latches the same in said position by releasing the lever 16 and permitting the pin 18 to engage with one of the holes 12 in latching bolt 11, any number of which may be provided, only three being shown in the device illustrated. The door is shown located in completely opened position in Figure 3 in the drawings. If it is desired to swing the door further than the position shown in Figure 3 the operating lever is depressed, and the door is swung and latched as heretofore described. To prevent the latching bolt from sliding from its guide slide into an inoperative position the abutment plate 20 is swung into operativeposition as shown in Figure 1. It is readily seen that engagement of the bolt 11 with the abutment plate 20 will prevent the latching bolt from over-riding and consequent disengagement with its guide slide 13.

When it is desired to render my device inoperative to permit the door to swing freely on its hinges unhampered thereby, the abutment plate 20 is pivoted on pivot member 22 to a position opposite to that shown in Figure 1 thereby permitting the latching bolt to slide through the aperture in the staple member 23 and thus become disengaged from its guide slide 13 in door 1. The latching bolt 11 can then be swung on its pivotally mounted member 7 to an out of the way position permitting the operation of the door uninfluenced by my invention.

I claim 1. In a closure fastening mechanism,'means for stopping and holding a door at predetermined opened positions thereof, comprising a movable member pivotally swingable on the door-jamb, .a guide having a slot on said door in which said movable member is slidably mounted and means for holding said movable member against disengagement from said guide slot comprising a pivotally mounted stop member adapted to be movable transverselyof the path of movement of said movablri.l member for abutting engagement therewit 2. In a closure fastening mechanism, means for stopping and holding a door at predetermined opened positions thereof, comprising a movable member pivotally swingable on the door-jamb, a guide having a slot on said door in which said movable member is slidably mounted and means adapted to hold said movable member against sliding movement relative to said guide slot, whereby said movable member is retained in said slot, means for holding said movable member against disengagement from said guide slot comprising a stop member adapted to be thrown transversely of the path of movement of said movable member for abutting engagement therewith.

3. In a closure fastening mechanism, means for stopping and retaining the door in variable opened positions, comprising a reciprocating movable member positioned on the outside of said door and adapted to secure said door in variable positions when placed at variable points in its path of reciprocation and a stop for preventing overtravel of said movable member comprising a limiting member and a pivotally mounted plate adapted for engagement with the limiting member and for abutment with said movable member in its operative position.

4. In a door closure fastening mechanism, a reciprocating movable member carried by the door and operable upon swinging movement of said door, means for stopping and retaining said door in variable opened positions, a staple bracket mounted in the path of travel of said movable member and having upper and lower legs, a pivotally mounted plate upon said upper leg adapted for swinging movement to position said plate upon one side of said leg members to prevent overtravel of said movable member, and to a position upon the opposite side of said leg members to permit movement of said movable member through said staple bracket.
